`My invention relates to fasteners wherein it is desired to provide a fastener which is adaptable for various uses and of a simple nature, inexpensive yet very practical for the use for which it is designed.

It is very desirable to have a fastener for windows and this is particularly true in lake cottages and other residences where it is desired to open the windows and hold the same in locked position so that they cannot be moved, thuspermitting the window to be opened from the top and bottom, or from the top alone, or bottom, and locking the window in this set position so that they cannot be moved until my fastener is disengaged from the same. A feature resides in a fastener made of a thin, flat strip of spring material, havinga curved body portion from which project engaging ends so that when the fastener is placed in position for use,these engaging ends will bite into the window sash and hold the window firmly in place. My vfastener forms a very practical means for preventing windows from rattling in addi` tion to the advantage of providing a fastener which is adapted to hold the window in any adjusted open position or to also hold the window locked in closed position.

The invention includes a fastener having peculiar `shape with the body curved in one form and from which project engaging members, while the end of the fastener is bent in a manner so as to form means for engaging a window frame or sash to hold the same rigidly in place. rllhe thin, flat sheet-like nature of my fastener provides a device which is very flexible and easily inserted between the sash and window casing or between the adjacent sides of the window sash when the windows are in partial open position. K

My invention also includes a fastener formed of a flat, thin nature and having longitudinally entending re-inforcing ribs eX- tending through vthe same so as to stiifen the body and end of the fastener and to permit the fastener to be made of very thin spring material.

A feature of the `invention resides in Vproviding a fastener with engaging members of graduated lengths so as to cause the engaging members to come into operative position with the parts which the fastener is attached to or inserted between. In this manner my fastener provides a very simple yet effective fastener and stop for holding a window or the sash ofthe window in adjusted position, locked against movement which permits the sash to be held in open position either from the top or the bottom, or both, and yet preventing anyone from movingl the window when my fastener is inserted or until the fastener has been removed from operative position.

My fastener is equally well adapted to be used for .holding doors or other articles in a set position and the fiexible nature of the fastener, together with its simple constructi-on and the fact that it is made of very thin material, so that it will flex sufficiently to be slipped between two articles which are positioned closely together or between a very narrow space, adjusting itself vto the extent of engagementl` provides a household utility which is very desirable.

In the drawings forming partof my specification:

.Figure lillustrates a'window frame show ing my fastener in operation, positioned between the over-lapping sidesof a window sash.

Figure is a side view of the same.

`Figure 8 is a flat view of one side of the same. Figure el illustrates a detail of a window frame and sash, showing my fastener used on the lower sash where the upper sash is tired, thus forming a. window fastener which is very effective.

Figure 5 illustrates the fastener removed from the window as constructed and illustrated in Figure il.

`Figure G illustrates another form of my invention.

Figure 7 illustrates a different form of my invention.

Figure 8 is a flat view of Figure 7- Figure 9 is an end view of Figure 7.

My fastener A is formed of spring material, having a body portion l0 of a very thin,

flat nature to provide a resiliency so that the .fastener A can be inserted readily between the frame and window sash, as illustrated in .Figures 1 and 4.

V In Figure 1 I have illustrated my fastener A positioned between the over-lapping inner portions of the window sash B and C which are held in the frame D. This use of my fastener' A holds the sash B and C against movement with the window open at E. It is apparent that before my fastener A is inserted between the sash B and C that the sash C can be dropped from the top of the frame D so as to open the window from the lower part at E and at the top F, so as to give top and bottom circulation in a room, and by inserting my fastener -A in between the over-lapping sides of the sash B and C, I provide a fastener which is very inconspicuous in use and is adapted to positively and firmly hold the window locked in any adrjusted open position in relation to eachother. W'hile I have illustrated only one fastener A in Figure 1, it is obvious that another' fastener A can also be used on the other side of the sash B and C, thus pr-oviding a very rigid and strong locking means for holding. the window sash B and C in adjusted open position.

My fastener A is provided with a gripping end 11 having engaging points 12 formed thereon by bifurcating the end 11 of the stop A. The end 11 is'bent approximately at right angles to the body portion 10 and as illustrated in the drawing, the body portion 1() is formed preferably with a curved .shape throughout its length, thereby providing a fastener A with a very active nature in use. The curved bodyr portion 10 causes the gripping points 12 to be forced into the center of the frame D when the fastener A is in use, with Vsufficient pressure so as to firmly hold the fastener A in place and against free disengagement. In the use of the fastener in this manner the points 12 are driven into the sash so as to grip the same andv hold the fast-ener in place even though the lower sash B were forced or pulled shut, the fact that the tongue end 13 of my fasl tener A is partially inserted between the sash prevents the fastener from becoming disengaged and thus forming a very practical window fastener.

rIhe tongue end 13 of my fastener A is smooth, thin and fiexibl'e and in fact the fastener A is of a very thin nature throughout its length as I have stated'heretofore. The smoothA tongue permits this end of the fastener to be inserted between the window frame and sash or between the sash sides of the two portions of the same and then by raising or opening the window to the desired point the biting and gripping ends 12V are forced into the same .so as to hold and lock the windows in place.

To assist in holding the fastener A I provide graduated gripping points 14 and 15, the length of the gripping point 14 being less than the gripping point 15, and the `gripping point 15 being of a less 'height or length than the gripping points 12, so thatV if the stop A is forced into position between two objects and is fiattened out Afrom thel l tending along the marginal edge of the fastener A and illustrating one gripping point 14 formed therein. Obviously this form of my fastener operates equally as well as the construction illustrated in Figures 2 and 3 and I have illustrated this form of my fastener being used in Figure 4 to provide a fastened for the lower sash B of the Window to prevent the same from being lifted, and,

thereby providing a very economical loclring means for lake cottages and the like. In this use of my fastener A the upper sash C. is fixed against movement and is notI ordinarily moved in the frame D.V I have had reason to use my fastener A in this manner" and as an anti-rattlingdevice for windows or doors and to hold doors in a` set open position, and I have fund the same to be very rpractical yet of an economical nature so that I am having considerable demandfor my device. i

In Figures Z to 9 inclusive, I have illustrated my fastener A witha comparatively straight body portion 10, yet of va very thin flexible nature and provided with the engaging members 14 and 15 which co-operate with the gripping ends 12 to hold this fastener rigidly in place. The smooth, thin end 13 forms a tongue forstarting the fasy tener into position between two articles and" to permit it to freely slide until the members are brought together so that'the gripping ends, together with the members 14 and 15 operate to hold the lock set in a position to form a stop when it is in use.`

There are many practical uses for my fastener but I desire to have it understood that while I have illustrated a particular form and construction 4of the same which is primarily in a very thinA flexible flat ribbonlike memberL withV gripping members formed Vtherein and of an integral nature,jit is obvious that the fastener may be adapted to other uses than those set'forth and varied vin construction withinthe scope of the ap,-`
